SPECIFICATION forming part of Letters Patent No. 408,589, dated August6, 1889.

Application filed May 4, 1889. Serial No. 309,575. (No model.)

To all whom it may concern:

Be it known that I, FRANK P. ORA1G,a citizen of the United States,residing at Holton,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same.

The invention relates to improvements in corn-cultivators, beingespecially adapted to cultivate listed corn; and it consists in theconstruction and novel combination of parts hereinafter described,illustrated in the accompanying drawings, and pointed out in theappended claims. 4

Figure 1 of the drawings represents a perspective view of a deviceembodying the invention. Fig. 2 represents a modification thereof indetail, and Fig. 3 represents a central longitudinal section through theleverhandle and sleeve.

Referring to the drawings by letter, A designates the main frame of themachine, consisting of the runners at, of ordinary construction andparallel to each other, and the transverse beams a' a secured to thetops of the runners, respectively, near the front and rear ends thereof.To the front beam a is secured the tongue, of any desired construction.

a is the drivers seat, resting on standards rising from the tops of therunners just in front of the rear beam (L as shown. The runners may, ifdesired, be adjusted nearer together or farther apart by means ofopenings in the transverse beams a 0, and pins or bolts that passthrough said openings into registering openings in flanges on therunners.

a a are harrow-teeth that incline downward and rearward and pass throughand are secured in series of openings (one or more in number) arrangedin line in the beam a adjacent to the ends thereof. The beam a is longerthan the beam (1 and extends on each side equal distances farther outthan the latter.

B B are bars perforated at each end and engaging at said ends theadjacent end of S- shaped hooks b, the opposite ends of which areengaged in openings 1), arranged in line along the facing edges of thebeams a o The openings 1) in the beams a are equal in number to the barsB; but there are half as many again of said openings in the beam a, sothat the inclination of the bars B, which stand forward and outward fromthe beam a can be changed by inserting the hooks 1), connecting to thebeam a, into openings farther inward or outward.

b b are harrow-teeth inclining downward and rearward and passing throughand secured in series of aligned openings in the bars 13.

C C are plow points the standards of which pass upward through any oneof the series of openings 0 near the ends of the beam a and are engagedthereabove by the nuts 0, so that the said points can be adjustedoutward and inward.

D is a transverse shaft journaled in standards rising from the beam anear the ends thereof, and having one end bent at right angles to theouter side of one ofsaid standards, preferably the one on the rightside.

E is a curved or semicircular rack rising from the beam a to the outerside of the shaft D, and e is a lever-handle secured to and rising upfrom said portion and having a springlatch.

G are arms provided with the perforated or slotted heads 9 at theirouter ends and the sleeves g at their inner ends, which sleeves surroundthe shaftD and maybe moved closer together or farther apart thereon andthen fixed in position by the set-screws 9 which pass throughinternally-threaded bosses on the sleeves.

g is an opening at a suitable point in each arm G, the series ofopenings 9 in the head of said arm being concentric with said openings 9H H are plow beams or standards, having their inner portions h straightand their outer portions about semicircular, to the ends of which outerportions are suitably secured the plow-points h. The ends of thestraight portions it are pivoted, by bolts or otherwise, to thecorresponding openings 9 of the arms G, and they are provided with anopening that registers with any one of the corresponding series ofopenings 9 so that by means of the openings 9 and bolts or pins 7L2 thebeams H can be set at diiferent angles 011 the arms G.

By means of the lever-handle, rack, detentbar thereof, shaft D, and armsG the beams H and plow-points h can be elevated, so that they will nottouch the ground when it is not desired to operate them.

I is a shield bent longitudinally and centrally downward on each sideand connected by the arms 1' to the runners, which arms are pivoted attheir front ends upon, the rear portions of the runners, as shown. Thesaid shield prevents the soil from being thrown too far inward by thepoints h. The shield is connected to the curved part of the runners bythe chain K, the ends of which are engaged in openings in the highestparts of said curved portions, while its middle portion passes through aring secured to the top of the shield.

If desired, the bars B may be detached and the machine operated withoutthem.

In the modified form shown in Fig. 2 the harrow attachment has on theinner side the eyebolt b engaging on the rods L, secured to the side ofthe runner, so that the said attachment can be moved at this side up anddown 011 said rods. This construction also serves as a hinge to enablethe attachment to be tilted or lifted sidewise by means of the chain M,which leads to a point near the drivers seat, and thus allows theattachment to pass over stones or the trash to fall away from it.

The joints formed by the S-shaped hooks permit the removable bars toswing or twist laterally, so that the teeth Z) can turn to one side, outof the way of obstructions.

Having described my invention, I claim 1. In a corn-cultivator, thecombination, with the main frame composed of the runners and thetransverse beams 01/ a of the removable bars B, extending inward andrearward, provided with the barrow-teeth b and connected to the beams aa by flexible joints, so that the said teeth can turn laterally out ofthe way of obstructions, substantially as specified. I

2. In a corn-cultivator, the combination, with the shaft D and means,substantially as described, for rotating the same to and holding it in adesired position, of the arms G, provided with the heads g, having theopenings 9 having the openings g at proper points,

and provided on their inner ends with the sleeves g, the set-screws g tohold the sleeves in proper position on the shaft D, the plowbeams havingin their straight portions 71- openings registering with the openings 9and the pivotal pins or bolts 7Z2, substantially as specified.

3. In a corn-cultivator, the combination, with the main frame providedwith the runners a, of the arms G, turning on the shaft .1), theplow-beams ll, vertically adjustable on the arms G, the shield I, withits arms v1 pivoted on the rear ends of the runners, and the chain K,connecting the beams II and shield I, so that the latter will rise withthe former, substantially as specified.

In testimony whereof I aiiix my signature in presence of two witnesses.

FRANK P. CRAIG.
